It could be a good explain Dren.
But from this picture, we can see Schumacher's car also changed from Saturday to Sunday.
They were covered the exits on the top of the side-pod.
What is strange to me, is that after Valencia, I read an interview with somebody (maybe it was Martin Witmarsh), and he was explain his indignation because the FIA change the parc fermé rules after the extreme engine mapping settings and it means they simply can't change anything on the car between Saturday and Sunday.
But from the pictures above, it's not the situation.
Anyway, thanks guys for the tips!
